use of net.runelite.api.WorldMapManager in project runelite by runelite.

the class Hooks method checkWorldMap.

/**
 * When the world map opens it loads about ~100mb of data into memory, which
 * represents about half of the total memory allocated by the client.
 * This gets cached and never released, which causes GC pressure which can affect
 * performance. This method reinitailzies the world map cache, which allows the
 * data to be garbage collecged, and causes the map data from disk each time
 * is it opened.
